I am all in favour of progressive enhancement and using server-side rendering when fetching a URL. The age-old discussion gives several advantages, such as improved load time, SEO crawling and possibly an improved level of "correctness"...etc
However I am getting my doubts as to why I am also setting up my server-side to handle form submits (i.e. a native HTML form being submitted to the server).
What are the advantages in handling server-side POST or when should it be a priority?
